SANYO LC372100PT-20LV, LC372100PT-10LV, LC372100PP-20LV, LC372100PP-10LV, LC372100PM-10LV Datasheet

Overview

The LC372100PP, LC372100PM and LC372100PT are
262,144-word × 8-bit organization (2,097,152-bit) mask
programmable read only memories.
The LC372100PP-10, LC372100PM-10 and
LC372100PT-10 feature an access time of 100 ns, an OE
access time of 40 ns, and a standby current of 30 µ A, and
are optimal for use in 5-V systems that require high-speed
access.
The LC372100PP-20LV, LC372100PM-20LV and
LC372100PT-20LV feature an access time of 200 ns, an
OE access time of 80 ns, and a standby current of 4 µ A,
and thus are optimal for use in 3-V systems that use
batteries. Additionally, they provide high-speed access in

3.3-V systems (3.0 to 3.6 V) with a 150-ns access time
and a 60-ns OE access time.
These ROMs adopt the JEDEC standard pin assignment
which allows them to replace EPROM easily. To prevent
bus line collisions in multi-bus microcontroller systems,
pin 24 can be mask programmed to be either active high or
active low.
